Personally I like Mak's VA service because using a number in a domain name can be confusing. For example should it be VA4Hire or VAforHire. I just read a great eBook on this subject and one of the rules for domain naming is to avoid numbers as words because people may get confused about what to type.
Also using Mak's is a tad more personalized which some potential clients look for. After all it is about building relationships with your clients.

I agree with Lee as far as using a number in your name, especially your domain name. I also agree with her point about personalizing the business name. When I look at the name that is capital letters with numbers, I don't get any kind of "feeling" or inspiration. It sort of reminds me of part of an algebra equation. Of course, I am an English major, so that may be where my shyness of numbers comes from.
